Question

A body travels with the speed of 10m/s for 10 sec and then with the speed of 20m/s for the next 10 sec.Calculate average speed of the car?

Answer 1

Average speed=total distance/total time.

So total distance is 10*10+20*10=300m.

Total time is 20sec. Plug in and get the answer.

It is15m/s.

Answer 2

since here time is same so here formula is Average speed =sum of speed / no. of speed. Average speed = (20+10)/2 = 30/2 = 15 m/sec. Other wise we can use general i.e. Average Speed = total distance / total time taken. Thank you for asking this question. Please mark me as brainliest.
